Application 'flled September 24, 1919. Serial 170.3%,051.

To all whom; it may concern:

Be it known that we, HARRY 0. DE BAUN,

MACK M. Scnwnn and CoRNnLUs KERKHOF, citizens of the Ijnited States,residing at Hackensack, in the county of Bergen and State of' NewJersey, have invented certain new" and useful Improvements in PaperBottles, of which the following is a specification. I

"The object of this invention is to provide a non-breakable bottle .oranalogous container', especially for liquids, which will be.

inexpensive to manufacture and so constructed that it will withstandblows or strainsthat might rupture thesame andresalt in loss of itscontents and will insulate its contents from heat or cold and which mayif desired simulatemilk bottles of the type now in common use,especially to the end that provision shall be made for the seating of apaper disk closure in the mouth of the container and the application ofa mouth sheath'or cover.

In the drawings, 7

Figure 1 shows the completed bottle 1n side elevation, the walls of itstwo main member's appearing partly broken awzgy;

Fig. 2 is a vertical sectional view 0 the two main members preliminaryto forming the container mouth and bottom;

Fig. 3 is a plan, showing the protecting mouth sheath,- partly brokenaway, and the sealing disk;

Fig. 4; shows .the mouth portion, partly broken away;

i Fig. '5 is a vertical outer or housing member;

Fig. 6 is'a side elevation, partly broken away, of the inner or receivermember;

Fig. 7 is a plan, and Fig. 8 a horizontal sectional view of the receivermember.

' To form the container shown in the drawings its principal elements arepreferably composed of paper of cod thickness and sufliciently charged,as y. impregnatmg, with paraflin or equivalent waxy material, plastic atleast under heat, so that it.

will take and permanently hold any shape that may be imparted to it bydies or molds, as for example, bends,;crimps, upsett ng and the like; ofcourse, in selecting the waxy material, whatever it is, it is chosenwith a view to make it suitable with respect to the contents, as milk,for which the container is to be used.

sectional View of the There are two main elements or members, a and b,each generally tubular in shape and, n the present instance, each havingin its mitial form more or less the side elevational shape of anordinary milk bottle to the extent, at least, that for the major portionof its lengthdt is cylindrical and of onediameter, and for anotherortion cylindrical but of less diameter, wit a ta r joining the twocylindrical portions. Th body portion of member a, marked a, is somewhatgreater in diameter than that, marked 6, of member b, but the neck orupper portion, marked a, of member a, has about the same inside diameteras the outside diameter of the neck or upper portion 6" of member 6.

The outer member as it is above described is complete for the operationof assemblin the two members ashereinafter explame The inner member I),however, is preliminarily formed with longitudinal crimps or the(assembled) members a and b converge;

T these ribs in side elevation are beveled away at their upper ends,conforming to the inside shape of the member a. Member I) also has anlnternal circumferential crimp or fold, producing a rib or flange e. Tocomplte member 6 as shown, thus to make it a. receiver memberopen at thetop and closed at the bottom, there is a disk f which bears up againstthe rib or flange e, being'held thereagainst by folding inwardly andupwardly the 10 er edge portion 9 of member 6, the .fold being a sharpor direct rebend and the edge 9 squarely abutting the disk,

so that it is clamped uniformly all around between said flange and edge,the soft waxy nature of the waxed paper together with this clampingaction sealing any interstice that otherwise might permit leakage. Thejoint, however, may if desired or necessary be specially treated toinsure perfectly seal ing the same. v v Having thus formed the members aand b the member 6 is introduced into member a as shown in Fig. 2, itsupper end portion 6" then snugly fitting the-upper end portion a" ofmember a, and its ribs 0 at their edges bearing throughout their lengthagainst 110 member a, so that they serve as radial spacers between thetwo members.

In this connection it will be observed that on account of thedouble-walled form of the container, with the spacing ribs 0, theContainer is exceedingly well adapted to withstand sidewise crushingstrains.

To support the member I) in member a preferably a disk It is introducedinto the bottom of member'a and arranged to bear against therebentbottom edge of member I), whereupon the bottom edge '5 of member ais returned and upbent against the disk- Fi 1.

n forming the mouth of the container it is preferable to. provideathickened-up portion or lip to give a finish and afford means forattaching some covering device, as for instance a protecting sheath j,and also, in

the case of a milk bottle, for example, to provide within the mouth acircumferential seat for a paper sealing disk is or equivalent.

All the operations of forming crimps, bends, and the like are or may beproduced by dies in the presence of heat, the material settingpermanently in the shape given it by the die due to the waxy nature ofthe substance with which the paper is treated. This treatment is appliedin forming the mouth, which has the thickened-up shape, presenting anoutwardly projecting lip, indicated at Z in Figs. 1, 3 and 4; that is tosay, by suitable dies, the upper edges of the members a and I) beingprimarily as in Fig. 2, said edges are by the pressure of a superimposedupsetting die member anda surrounding underneath supporting andlip-forming die member crushed and reformed into the shape 1 shown bestby Fig. 1, the result being in effect to weld the two paper layers intoa single ringshaped mass, especially in view of the presence of heat tofuse thwaxy material.- The upper die (or it may be another tool inaseparate operation) may form the seat m for the disk Z.

When the article has been formed as de scribed, i. 6., with the receivermember I) within and held spaced from the housing member a, by the ribsc and also held against longitudinal shifting relativelyto the hous' ingmember by being clamped between the tapered portion of member a whereribs 0. or equivalent limited-contact projections bear against the sameon the one hand and theinturned edge 11 and disk 72, on the other,

and by the shaping of the upper edges ofsaid members into the lip Z, acontainer is produced which is obviously exceedingly strong and lightand inexpensive to manufacture.

It will be observed that the air which is contained within the spacebetween members a andb serves as heat insulation, to keep the contentscold or warm as the case may be.

. support Circulation of the air around member I) may be permitted byperforating ribs 0, as at n.

Having thus fully described our invention, what we claim as new anddesire to secure by Letters Patent is i 1. A container including aninner tubular receiver member closed at the bottom and open at the topand a tubular housing mem ber inclosing the receiver member, one mem--ber having an upward taper and the other projections bearing againstsaid taper, and the housing member thus afiording a stop to upwardmovement of the receiver member and having its bottom portion holdingsaid receiver member pressed upwardly against said stop.

' 2. A container including an inner tubular receiver member closed atthe bottom and open at the top and a tubular housing members havingconcentric upward tapers and one member having projections bearingagainst the taper of the other member, and the housing member thusaffording a stop to upward movement of the receiver member and havingits bottom portion holding said receiver member pressed "upwardlyagainst said stop. I

- 3. A container including an inner tubular receiver member closed atthe bottom and open at the top and a tubular housing mem-' ber inclosingthe receiver member, one .mem-

ber having an upward taper andthe other longitudinal ribs bearingagainst said taper, and the housing member thus affording a stop toupward movement of the receiver member and having its bottom portion andbearing against said taper, and the housing member thusaflording a stopto upward movement of the receiver member and having its bottom portionholding said receiver member pressedupwardly against said stop, saidribs bearing below said, taper against the member having the taper.

5. A container including an inner tubular receiver member closed at thebottom and 1 7 open at the top and a tubular housing mem ber inclosingthe receiver member, one mem- I her having an upward taper and the otherprojections bearing against saidtaper, and

the housing member thus affording a stop to upward movement of thereceiver member and havin at its bottom portion an inward olding saidreceiver member pressed upwardly against, said stop.

6.
